Kalokol used to be known as Ferguson's Gulf, co ordinates are N03 29 46, E035 50 26. Its about 1245' above sea level, runway is 12/30 and USED to be tarmac. Used to be being the operative word. Not too much used these days.
Security is variable. But not usually an issue for an aircraft parked on ground - except there is a local issue going on between the local tribesmen and an oil drilling company. Things got a bit heated in the last few days, so how this might affect security is unknown.
Air Traffic at Wilson are the main operators in this area, and they would be best placed to answer more thoroughly I guess.
Enjoy the heat and dust when you get there!
